Description

Compound rebar connector

This creation is about a reinforced steel splice, especially a composite reinforced steel splicer suitable for joining two reinforcing steel substrates.

Reinforcing steel bar connection is one of the most common construction methods in construction projects. In recent years, the height of bridge piers has increased and the construction of high-rise buildings has become more and more common. Indirectly, the use of domestic steel reinforcement connectors has increased dramatically. However, the length of the steel bar is generally limited by the manufacturing site and the site of the handling process, and all have a fixed length range. The construction site has to use a continuous connection to increase the length of the steel bar to meet the actual construction needs. The quality of the reinforcement connection will be related to the seismic strength of the building.

At present, the common common steel bar connection methods are as follows: 1. Traditional manual lap method, 2. Gas compression method, 3. Thread connection method, 4. Hydraulic sleeve connection method, 5. After head expansion Continuous connection method of turning or rolling teeth 6. Continuous connection method of friction welding. The types of reinforced steel splices that are commonly used in China are the threaded splicing method, the expansion of the rear teeth or the rolling method... and other mechanical steel splicing methods.

The structure of the mechanical splicing device mainly includes: a connector or a connecting sleeve or other components to complete the connection of the two steel bars. With the improvement of construction technology and the consideration of its quality and efficiency, the mechanical steel bar continuous connection method can not only be effective It improves the convenience of construction, and can enhance the strength of the steel bar grip, and avoid the phenomenon of concrete honeycomb and artificial lashing, so it gradually replaces the traditional artificial lap joint construction method and is more widely used by the construction industry.

Please refer to FIG. 1, FIG. 2A, FIG. 2B and FIG. 2C, which are respectively an exploded view of a conventional rebar splicer screwing two rebar base materials, a schematic diagram of the initial step of screwing, a schematic diagram of simultaneous screwing and a schematic diagram of screwing completion. The above-mentioned conventional steel bar splicer 1 can be applied to the steel bar continuous construction of beams, columns and slabs in construction projects to join two steel bar base materials 3 and 4.

As shown in FIG. 1, the hollow connector 2 of the reinforced joint 1 has a hexagonal column shape, and a cylindrical through hole is dug inside; the inner ring surface of the hollow cylinder 2 has two locking parts, including A first locking portion 21 and a second locking portion 22. The inner annular surface of the first locking portion 21 has orthodontic threads 211, and the inner annular surface of the second locking portion 22 has anti-tooth threads 221, for screwing and connecting the two reinforcing steel substrates 3,4.

The two reinforcing steel substrates 3 and 4 joined by the above-mentioned conventional reinforcing steel connector 1, wherein the outer surfaces of the two ends of the reinforcing steel substrate 3 are respectively rolled out the counter-thread 31 and the ortho-thread 32 by a thread rolling machine; The outer surfaces of the two ends of the base material 4 are rolled out by the thread rolling machine to the counter-thread 41 and the ortho-thread 42. Since the above-mentioned conventional reinforcing steel connector 1 adopts a screwing method, the second locking portion must match the corresponding threaded end of the reinforcing steel in order to be smoothly assembled. In addition, at the end of the second locking portion 22, there is a notch mark 23 of a leading angle, which can be used to mark the internal thread of the second locking portion 22 as a counter-thread 221.

When the two reinforcing steel substrates 3 and 4 are continued, as shown in FIG. 2A, first, the reinforcing steel connector 1 is screwed into a tooth in the counterclockwise direction of the orthodontic thread 42 of the reinforcing steel substrate 4, and the reinforcing steel substrate 3 The counter-thread 31 is close to the rebar connector 1; then, as shown in FIG. 2B, the counter-thread 31 is rotated counterclockwise toward the counter-thread 31, and the counter-thread 31 of the two rebar bases 3 and 4 is connected to The orthodontic thread 42 is locked inward synchronously, and note that if the difference in the number of threads on both ends exceeds one thread, the rebar connector 1 must be rotated counterclockwise to loosen the two rebar base materials 3 and 4 before adjusting the thread Number of teeth; finally, as shown in FIG. 2C, when the counter-thread 31 of the reinforcing steel substrate 3 and the ortho-thread 42 of the reinforcing substrate 4 collide, it is the action of completing the rebar connection.

In order to achieve the purpose of connection, the above-mentioned conventional steel rebar splicer 1 must machine the teeth of the two fixed ends of the steel substrates 3 and 4 and also cause material loss to the steel substrates 3 and 4 due to processing. Tolerances have a great impact on the tensile performance, it is necessary to first transport the reinforcing steel substrates 3, 4 to the processing plant, and then to the on-site installation after processing is completed, and the installation process is quite time-consuming and labor-intensive, which is quite inconvenient for construction projects and not ideal There is still room for improvement.

After the adhesive is cured, it will reach the reinforcing steel base. The purpose of material connection can greatly reduce the assembly man-hours, and will not cause the loss of steel base material.

The first locking part and the second locking part respectively have a through hole and two positioning holes. The two through holes are used for pouring an adhesive to anchor the joint For the two reinforcing steel substrates, the four positioning holes are used for passing through four screw locks to fix the two reinforcing steel substrates.

Another purpose of this creation is to use the above-mentioned injection type chemical anchor bolts at one end of the composite reinforced steel connector when connecting the steel bars, and the conventional screw connection method is used at the other end. In this way, the assembly man-hours can also be reduced. Reduce the loss of steel base material.

In order to achieve the above purpose, the composite reinforced steel splice connector of the present invention is used to join two reinforced steel substrates.
